Exposure Lights Maxx-D 17 is a high-output, smart front light built for fast night riding, with REFLEX 4850 lumens and efficient power management. A refined beam pairs two 16° spot LEDs for reach with a 45° 15° oval lens for wide cornering vision. Runtime spans 2 36 hours and the unit weighs 326g. OSD+ gives clear, full-colour ride data, and power bank mode lets you charge devices from the light. USB-C PD delivers quick, simple charging.Key Features and Benefits:REFLEX 4850-lumen adaptive output: Onboard 3D accelerometers, a gyroscope, and thermistors sense speed, movement and heat to boost light at pace and dim on climbs. You get extra brightness when needed while still meeting the selected runtime by averaging output over the period.Refined beam with 2 × 16° spots + 45° 15° oval lens: The spots project long-range light for reading the trail ahead, while the oval lens spreads light across the turn. You see further and wider at the same time, so corner entry and exit remain clear at speed.2 36 hour runtime range: High modes cover short, intense rides; low modes support multi-day efforts. You match output to distance and conditions with no mid-ride surprises.OSD+ full-colour display (70% larger): Bright, easy-to-read status for mode, remaining time, and charge level. You make quick decisions without guessing, reducing stops and battery anxiety.USB-C PD charging: Faster top-ups and one-cable convenience at home or from portable power banks. Downtime drops and the light is ready sooner for the next ride.Power bank mode via USB-C: The light can charge phones, GPS units, or action cams. Navigation and comms stay available when rides run long.ITM thermal management: Patented control reduces LED power if temperature rises, then restores output when cooled. Efficiency stays high, protecting LEDs and preserving battery capacity.OMS (Optimised Mode Selector): Pre-set programs make it easy to choose run times and patterns, including a fixed 3000-lumen high mode. Setup is fast, and output stays consistent with your plan.The goal is clear, stable speed in the dark with minimal fuss. The wide-and-long beam supports fast lines. REFLEX adds brightness during hard efforts without breaking your runtime plan. OSD+ keeps time-to-empty visible, ITM guards efficiency, and OMS lets you pick a program that fits the ride. USB-C PD and power bank mode add simple charging on and off the bike.Choose Maxx-D 17 for adaptive 4850-lumen power, a beam built for speed, and control over every watt and minute. Select your mode and ride with consistent light, clear data, and straightforward charging.
